Abstract
A processor which includes separate instruction and data caches and which executes instructions according to a new instruction set architecture efficiently executes software code by providing the processor with a grouper circuit which receives software code instructions from a secondary memory and groups these instructions based upon the content of the instructions and provides these grouped instructions to the instruction cache of the processor. In this processor, the old instruction software code conforms to an old instruction set which is a subset of the new instruction set. Such a system also functions where the processor maps instructions to itself
